Teck Resources Ltd

Through this review, we seek to provide greater transparency to our approach to working with associations on climate action. The objective of this review is to identify and report the degree to which the climate change positions and actions of associations deemed to be in-scope (outlined on page 9 of this report) are aligned with our Climate Change Guiding Principles (outlined on page 7). [...] This review establishes a robust framework for ongoing and future association reviews and disclosure as well as internal governance as it relates to how we manage our association memberships, including in cases where associations are not aligned with our Climate Change Guiding Principles. In such cases, Teck will engage directly with these associations to better understand their positions and actions, then advocate for better alignment with ours. When differences cannot be reconciled, Teck may choose to withdraw from that association. [...] Members of Teck's Government & Regulatory Affairs, Corporate Affairs and Environment groups lead our direct and indirect engagements with governments on the issue of climate change. [...] Teck engaged a third-party consultant, Kirk & Co. Consulting Ltd., to undertake a comprehensive audit of the 16 associations scoped into this review, and to determine their level of alignment with our Climate Change Guiding Principles. This audit included a review of website content, annual reports, public documents, announcements and other materials. [...] Where there were gaps in response, Teck initiated direct engagement with each of the 16 in-scope associations. Through conversations and a questionnaire, Teck sought to validate the desktop findings and collect outstanding information. Of the 16 relevant associations, most completed the questionnaire before the deadline to respond. Associations that did not participate in the questionnaire were assessed on the information provided in the direct conversations and the information available through the website audit.

Our Board of Directors is responsible for the stewardship of our company and ensures that appropriate corporate governance structures and systems are in place. The Board approved our Climate Action Strategy as well as this report. [...] Our Board and senior management are actively involved in assessing climate-related risks and opportunities. This includes incorporating climate-related considerations into corporate-level strategies and capital investment decisions. At the asset level, risks and opportunities are identified throughout the project planning phases. For example, projects above $50 million typically conduct assessments of risks associated with energy use, GHG emissions and climate change. [...] Climate-related risks and opportunities are identified using risk management tools internal to Teck and rely on both internal and external expertise on climate change aspects. These risks and opportunities are then prioritized based on their likelihood of impacting our business and the estimated severity of impact. [...] The Board approves our Climate Action Strategy and regularly assesses performance against climate and energy goals. The use of climate-related scenarios aids the Board and senior management in factoring climate-related considerations into our overall corporate governance and strategic planning.

Our Political Contributions Policy includes our commitment to zero corporate political contributions and to compliance with rules relating to election activities and attending partisan events. [...] As outlined in our Political Contributions Policy, Teck does not make use of corporate resources, including funds, goods, property and/or services, for the purpose of contributing to a political party, a campaign for elected office, a nomination process for a political party, a local political constituency and/or any individual candidate seeking election at any level of government. In 2023, we did not make any direct financial or in-kind political contributions. [...] Contributions to Industry Associations [...] Through our membership in various industry associations, Teck strives to advance research, share best practices and exert a positive influence in a manner that aligns with our company's values as well as those of our employees, stakeholders and shareholders. In 2022, we published our first Industry Associations Review, to identify and report the degree to which climate change positions and actions of selected associations are aligned with our Climate Change Guiding Principles. We expect to conduct similar reviews regularly in the future.

Teck's Board of Directors is responsible for the governance of climate change issues, including risks and opportunities. Implementation of this policy is overseen by Teck Senior Management.

#### Our Approach to Lobbying

###### With respect to climate change and nature-related government policies and regulations, we engage directly with governments and indirectly through industry associations. Members of Teck's Communications and Government Affairs lead our direct engagements with policymakers on the issues of climate change and nature. We regularly review our engagements to ensure that we take a position consistent with our climate change and environment policies, and with our commitments to the objectives of the Paris Agreement and the Kunming-Montreal Global Biodiversity Framework (GBF).

###### We engage policymakers in all jurisdictions in which we operate and/or have major projects, as well as other jurisdictions through our membership in various industry associations, such as the International Council on Mining and Metals (ICMM) and the Mining Association of Canada (MAC). We believe it is important to engage with industry associations to advance research, share best practices and exert a positive influence across the extractive sector and beyond.

We recognize that stakeholders expect strong governance and transparency as they pertain to the climate and nature lobbying positions of the membership organizations of which Teck is a member (disclosed on our website). We review industry association positions on climate change and nature, and advocate for their alignment with the Paris Agreement and the GBF. The ICMM, MAC and the Mining Association of British Columbia are the trade associations that have the most engagement on climate action, with the ICMM and MAC having the most engagement on nature. Teck has been directly involved with all three associations in establishing positions on climate policy, and with ICMM and MAC in establishing positions on nature policy. All three associations have Paris-aligned positions; the ICMM and MAC have explicit statements on the matter on their respective websites. Our climate advocacy and industry collaborations were published in our Industry Associations Review, which reviews our industry's climate change positions and actions. In January 2024, the ICMM released a nature position statement, to which Teck as a member is committed.

###### There can be a wide range of views within the membership of each association and, as members, we may not always agree with every position or approach. This is especially the case when the association's membership is large and the mandate is broad, covering a wide range of issues. This diversity of perspectives creates a rich and full debate. When disagreement arises, Teck may provide greater clarity on our own positions and activities with policymakers, work with the association to understand alternative points of view and to seek common ground for progress, consider our ability to influence policies or perspectives of the organization or, ultimately, consider whether to continue participating in the association.

We are also active in the World Economic Forum's (WEF) Champions for Nature, a CEO- and Minister-level leadership group that includes public and private sectors, civil society, academia and activism. The Champions for Nature community supports the nature positive transition by raising ambition, influencing narrative and fostering partnerships. We are also a signatory to Business for Nature's (BfN) Call to Action calling on governments to adopt policies now to reverse nature loss in this decade, and have contributed our nature strategy to BfN's It's Now for Nature campaign.

Describe the process(es) your organization has in place to ensure that your engagement activities are consistent with your overall climate change strategy[…]Teck's Board of Directors is responsible for the stewardship of our company and for ensuring that appropriate corporate governance structures and systems are in place. Overall accountability of our climate change positions and actions is assumed by the Sustainability Committee of Teck's Board of Directors.

With direction from the Sustainability Committee, Teck's Senior Management Team is responsible for overseeing and making decisions on the day-to-day engagement activities relating to climate change. This applies to all the jurisdictions where Teck operates. Given the multi-faceted ways in which climate change impacts our business, oversight and decision-making are often shared among members of Teck's Senior Management Team.

Prior to Teck employees conducting engagement activities relating to climate change (e.g., meeting in-person with public officials, speaking on panels, submitting written comments and recommendations, etc.), the approach and tactics involve approval from Teck's Senior Management Team. This oversight and approval helps ensure that the engagement activities are consistent with Teck's overall climate change positions and actions. It also helps Teck manage the multiple engagement activities relating to climate change across the company in all operating jurisdictions to ensure we have a common approach.
